Fog Lights Out

[Firelined89]

I have a 2018 Ram 2500 Laramie 6.7l diesel. The fog light switch is depressed and displays being "on" in the instrument panel. However, with the engine running, both stock fog lights won't illuminate. The brights are turned off and I've pulled both lamps and tested for continuity with a multimeter. The halogen lamps are good. I'm unable to locate the exact fuse or relay for the fog lights. I've gone down the rabbit hole on the internet and YouTube with no luck. Any recommendations would be greatly appreciated. TIA

Did you check if there was power in the socket while you had the bulbs out? If not I’d check that and check the ground too.

There’s no power going to the light socket. Ground to frame looks good. ‍

try f10 Body Controller / Exterior Lighting #2 for the fuse

now sure if it will help much but Circuits L89 & L90

what is interesting that I cant find the switch diagram with the foglight button as a circuit. Wondering if the "headlamp switch mux" has it mixed in
